In this configuration, the system returns a distinct \"User does not exist\" error message to the login form, regardless of the validate_username setting. This behavior allows malicious actors to determine which usernames exist in the system based on observable discrepancies in the application's responses.\n\n\nExploitation of this vulnerability could aid in brute-force attacks, targeted phishing campaigns, or other social engineering techniques by confirming the validity of user identifiers within the system."}],"metrics":{"cvssMetricV31":[{"source":"ed10eef1-636d-4fbe-9993-6890dfa878f8","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","baseScore":3.7,"baseSeverity":"LOW","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.2,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}]},"weaknesses":[{"source":"ed10eef1-636d-4fbe-9993-6890dfa878f8","type":"Secondary","description":[{"lang":"en","value":"CWE-203"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:wso2:identity_server:5.10.0:*:*:*:*:*:*:*","matchCriteriaId":"F4F126CA-A2F9-44F4-968B-DF71765869E5"},{"vulnerable":true,"criteria":"cpe:2.3:a:wso2:identity_server:5.11.0:*:*:*:*:*:*:*","matchCriteriaId":"2153AECE-020A-4C01-B2A6-F9F5D98E7EBE"},{"vulnerable":true,"criteria":"cpe:2.3:a:wso2:identity_server:6.0.0:*:*:*:*:*:*:*","matchCriteriaId":"7B81C488-69D0-4A5C-AEED-31869C1BF5CA"},{"vulnerable":true,"criteria":"cpe:2.3:a:wso2:identity_server:6.1.0:*:*:*:*:*:*:*","matchCriteriaId":"65CD2558-C60C-4296-8E96-D4D804C598F0"},{"vulnerable":true,"criteria":"cpe:2.3:a:wso2:identity_server_as_key_manager:5.10.0:*:*:*:*:*:*:*","matchCriteriaId":"6BB34405-A2F1-461A-B51B-E103BB3680A1"},{"vulnerable":true,"criteria":"cpe:2.3:a:wso2:open_banking_iam:2.0.0:*:*:*:*:*:*:*","matchCriteriaId":"D7C241A3-8EA0-41E4-ABF3-21B9D8E7A5BE"}]}]}],"references":[{"url":"https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2025/WSO2-2025-3983/","source":"ed10eef1-636d-4fbe-9993-6890dfa878f8","tags":["Vendor Advisory"]}]}}]}
